There is a little catch for the rudder "down" line on the right hand side of the Revo11 cockpit.
I confess that I took it off because somehow it was interfering with my pant leg during normal mirage drive operation. So naturally I lost it when I moved most recently.
Come to find that I REALLY need it now because the upgraded sailing rudder just will not stay down when I am out on the ocean or practicing sailing in the bay.
I looked in the Hobie catalog and didnt see a part number, so I dont know if I can find it on ebay?
If anyone in the lower states doesn't have need for theirs, can I offer to buy it off of you?
